  • 3GPP 3rd generation partnership project
  • PSS already defines a solution for the delivery of media files using HTTP, e.g., progressive download, in a way that is similar to streaming. Progressive download is both supported by PSS encoders/decoders (codecs) and protocols as well as by 3GP file format.
  • a 3GP file compliant to the progressive download profile usually fulfills the requirement for the interleaving of media tracks at an interleaving time intervals.

  • data delivery may be not optimized for short-delay playback.
  • TCP transmission control protocol
  • the use of HTTP over transmission control protocol (TCP) for real-time media streaming may pose drawbacks due to the use of aggressive congestion and flow control algorithms, the connection-oriented nature, the requirement of strict in-order delivery of packets containing media data, and the retransmission-based error control protocols, e.g., slow-start restart protocol.

  • a significant amount of network resources may be consumed for the transmission of un-necessary metadata.
  • the metadata is usually located at the start of the file.
  • the metadata is usually transmitted before the transmission of any media data.
  • Usability of progressive download for providing video on demand functionality may not be desired due to a lack of control over a progressive download session.
  • real-time HTTP streaming is achieved by progressively transmitting portions of metadata with corresponding chunks of media data.
